A 0.85 m³ initially contains water at 260°C and a quality of 0.75. A valve at the top of the tank is opened and allows for saturated vapor at 260°C to leave the tank. The tank is maintained isothermally during this process until the tank is filled with only saturated vapor at 260°C. What is the mass of steam that leaves the tank during this process? kg How much heated is added to the tank during this process. KJ
